[0002] As an important part of bridge engineering, bridge drainage pipes are mainly used to drain the accumulated water in time when it rains or when water accumulates on the bridge surface, to prevent water from penetrating into the bridge structure and to avoid damage to the durability and safety of the bridge. As a specific installation method of drainage pipes, they are distributed along the length of the bridge at the bottom of the bridge, and are connected to the top of the bridge through multiple longitudinal pipes, thereby collecting the accumulated water discharged from the top of the bridge. Through reasonable layout and design, the efficient operation of the drainage system is ensured, thereby extending the service life of the bridge and reducing maintenance costs.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0021] like Figures 1 to 8 A bridge drainage pipe lifting device shown includes: The vehicle body 03 is suspended outside the bridge crash wall 01 and is arranged to move along the arrangement direction of the drainage pipe 02. The vehicle body 03 provides a working position for operators at the bottom of the bridge; The lifting assembly includes a lifting frame 04 and a hoisting structure 05. The lifting frame 04 is installed outside the vehicle body 03 and includes a sliding part 041 and a rotating part 042. The sliding part 041 is connected to the vehicle body 03 in a linear sliding manner, and receives the up and down moving power provided by the winch structure 05; the rotating part 042 is rotationally connected to the sliding part 041 through a longitudinal rotating shaft, and the rotating part 042 carries the drainage pipe 02 loaded from the top of the bridge and moves when it is in contact with the sliding part 041, and rotates relative to the sliding part 041 after the drainage pipe 02 descends to the installation height, so that the drainage pipe 02 rotates from the outside of the vehicle body 03 to the inside.

[0022] The present invention solves the problem of complex structure and high cost of traditional drainage pipe 02 lifting vehicles by suspending the vehicle body 03 on the outside of the bridge crash wall 01, combined with the coordinated action of the sliding part 041 and the rotating part 042 of the lifting assembly. During operation, the vehicle body 03 moves along the arrangement direction of the drainage pipe 02, providing the operator with a working position at the bottom of the bridge. The lifting frame 04 drives the sliding part 041 up and down through the winch structure 05, and when the rotating part 042 and the sliding part 041 rotate through the longitudinal rotating shaft, the drainage pipe 02 is accurately transferred from the outside to the inside; not only does it simplify the equipment structure and reduce the equipment cost, but it also greatly improves the installation efficiency and flexibility in the space-constrained bridge construction environment.

[0023] Specifically, before using the above-mentioned bridge drainage pipe 02 lifting device to work, the body 03 of the device needs to be hung on the outside of the bridge crash barrier 01 to ensure that the moving direction of the body 03 is consistent with the arrangement direction of the bridge drainage pipe 02. The suspension of the body 03 should be firm and reliable to ensure that it will not shake or fall off during the movement and lifting process, thereby ensuring the safety of the drainage pipe 02 lifting operation.

[0024] After assembly is completed, the drainage pipe 02 can be lifted through the device. First, the vehicle body 03 needs to be moved to the set position on the top of the bridge. The set position should be set corresponding to the end position of the previous section of the drainage pipe 02, so that the operator can stand on the working position on the vehicle body 03 and realize the connection and assembly of the next section of the drainage pipe 02; the movement of the vehicle body 03 along the arrangement direction of the drainage pipe 02 can be achieved by an electric or manual drive system. During the movement, it can be controlled by the operator at the position above the bridge crash barrier 01, or it can be directly controlled by the operator at the working position of the vehicle body 03 at the bottom of the bridge to ensure that the vehicle body 03 can accurately reach the position where the drainage pipe 02 needs to be assembled.

[0025] Next, the operator can lift the crane frame 04 to the top of the sliding path of the sliding part 041 through the hoisting structure 05. The crane frame 04 is installed on the outside of the vehicle body 03, and is used to receive the drainage pipe 02 on the top and transfer it to the assembly position at the bottom of the bridge, and ensure its stability; the hoisting structure 05 provides power for the crane frame 04, driving the sliding part 041 to move up and down. Generally, the hoisting structure 05 is usually driven by an electric motor, and the operator can operate it through the control panel or remote control to ensure that the sliding part 041 can be smoothly lifted and lowered to the designated position.

[0026] When the sliding part 041 is at the top of the sliding path, the rotating part 042 is at the top of the bridge, and the operator can load the drain pipe 02 onto the rotating part 042 on the bridge to ensure the convenience and stability of loading the drain pipe 02; after the assembly is completed, the winch structure 05 drives the lifting frame 04 to descend until the drain pipe 02 descends to the installation height. In the process of carrying the drain pipe 02 and transporting it, the rotating part 042 is in contact with the sliding part 041 to ensure that the drain pipe 02 does not shake or fall off during the lifting process; during the lifting process, the operator needs to pay close attention to the position and status of the drain pipe 02 to ensure its smooth descent.

[0027] When the drain pipe 02 is lowered to the installation height, the operator can apply force to the rotating part 042 or the drain pipe 02 at the working position to drive the drain pipe 02 to rotate from the outside of the vehicle body 03 to the inside. During this process, the rotating part 042 rotates 0°~180° relative to the sliding part 041 through the longitudinal rotation axis, so that the drain pipe 02 reaches the inner side for assembly. During rotation, the operator must ensure that the rotation is smooth to avoid collision between the drain pipe 02 and the surrounding structure.

[0028] After the drain pipe 02 is rotated to the inside, the operator will install the drain pipe 02 to the predetermined position. During the installation process, it is necessary to ensure that the connection of the drain pipe 02 is firm and well sealed to avoid leakage and other problems in the future. At the installation position, the operator can use auxiliary devices to accurately position the drain pipe 02 and fix it with expansion bolts, thereby completing the lifting and assembly operation of a single drain pipe 02.

[0029] After the installation is completed, the operator needs to check the drain pipe 02 to ensure that its installation quality meets the requirements. At the same time, the lifting device must be checked to ensure that its components are working properly and prepare for the next operation. At this time, the operator can apply reverse force to the rotating part 042 in the working position to make the rotating part 042 and the sliding part 041 fit together again. After the vehicle body 03 moves to the next set position, the winch structure 05 drives the sliding part 041 to rise again, preparing for the next drainage pipe 02 lifting and assembly operation.

[0030] On the basis of the above-mentioned embodiment, the lifting frame 04 also includes a magnetic attraction structure, which is arranged on the rotating part 042 and / or the sliding part 041, and provides a set magnetic attraction force for the sliding part 041 and the rotating part 042 through a permanent magnet; a magnetic attraction structure is arranged on the rotating part 042 and / or the sliding part 041 of the lifting frame 04, for example, a permanent magnet is embedded or an annular magnetic attraction component is used, which can provide a stable magnetic attraction force during the lifting process, ensure the close fit between the sliding part 041 and the rotating part 042, and at the same time do not affect the rotation movement of the rotating part 042.

[0031] Specifically, the specific structural form of the magnetic attraction structure can be set as an iron adsorption plate on the end face of the sliding part 041, or an annular groove is opened on the contact surface of the rotating part 042 to embed the permanent magnet; it not only improves the stability of the lifting process, but also simplifies the operation steps and reduces manual intervention.

[0032] On the basis of the above embodiment, the rotating part 042 includes a base 0421, a carrier 0422 and a telescopic body 0423; The base 0421 is rotatably connected to the sliding part 041, the carrier 0422 radially limits the drain pipe 02 through the groove structure, and the telescopic body 0423 connects the base 0421 and the carrier 0422, and adjusts the distance between the base 0421 and the carrier 0422 by the telescopic length.

[0033] The base 0421, as the core component of the rotating part 042, is connected to the sliding part 041 through a longitudinal rotating shaft, providing stable rotation support to ensure that the rotating part 042 can rotate smoothly; the supporting body 0422 radially limits the drain pipe 02 through the groove structure to ensure that the drain pipe 02 will not shake or fall off during the rotation and lifting process, thereby improving the accuracy and safety of installation; the telescopic body 0423 can flexibly move the drain pipe 02 to the docking position with the end of the previous drain pipe 02 when assembling the drain pipe 02 by adjusting the distance between the base 0421 and the supporting body 0422, thereby adapting to drain pipes 02 of different diameters and lengths, thereby increasing the versatility and flexibility of the device; the combination of the base 0421, the supporting body 0422 and the telescopic body 0423 provides stable support and precise positioning for the drain pipe 02, thereby ensuring the stability of the drain pipe 02 during the rotation and lifting process, and improving the accuracy, efficiency, flexibility and safety of installation.

[0034] Specifically, the carrier body 0422 can adopt a U-shaped, V-shaped limit groove or a modular clamp structure, or a radial clamping device can be arranged in the groove structure, and the telescopic body 0423 is preferably a hydraulic push rod or a screw mechanism; so that the drainage pipe 02 can achieve dual control of radial limitation and axial adjustment during the lifting process, which significantly improves the installation accuracy and adaptability.

[0035] On the basis of the above embodiment, it further includes a limiting structure fixedly connected to the vehicle body 03, the limiting structure independently provides a limiting space, or, together with the vehicle body 03, provides a limiting space; The limiting space limits the sliding portion 041 and the rotating portion 042 to maintain a close fit during the movement of the lifting frame 04.

[0036] The limiting structure ensures that the sliding part 041 and the rotating part 042 always keep in contact during the movement, improves the stability of the device and the installation accuracy of the drain pipe 02, ensures the stability of the drain pipe 02 during the lifting and rotation process, and reduces the risk of deviation caused by vibration or wind, so that the applicability of the equipment in complex environments is significantly enhanced. Specifically, the specific form of the limiting structure includes a U-shaped limiting slot welded on the side wall of the body 03, which has a compact structure and reliable limiting.

[0037] On the basis of the above embodiment, the vehicle body 03 includes a frame structure 031 and a wheel assembly 032; The frame structure 031 provides a standing position and a position for linear sliding connection with the sliding part 041, and the wheel assembly 032 is fixedly connected to the frame structure 031; There are at least three groups of wheel assemblies 032 on the vehicle body 03 , each group includes at least two wheel assemblies 032 , and the three groups of wheel assemblies 032 are respectively attached to the outer surface, the top surface and the inner surface of the crash barrier 01 .

[0038] The frame structure 031 provides a working position for the operator and a connection position with the sliding part 041. The wheel assembly 032 includes at least three groups, which are respectively attached to the outer surface, top surface and inner surface of the crash barrier 01 to form a three-dimensional constraint, ensuring that the vehicle body 03 remains stable during movement and prevents tilting or shaking, thereby improving the safety and stability of the device, reducing the risks in construction, and ensuring the accuracy and quality of construction. Specifically, the specific structural form of the wheel assembly can be set to a universal wheel assembly or a spring-suspended wheel assembly, which can adapt to the uneven surface of the bridge crash barrier 01, improve the environmental adaptability and versatility of the device and the stability and safety of the movement of the vehicle body 03. At the same time, the wheel assembly 032 converts the sliding friction between the frame structure 031 and the crash barrier 01 into rolling friction, which facilitates the transfer of the vehicle body 03 and reduces the labor intensity of the operator.

[0039] On the basis of the above embodiment, the hoisting structure 05 is installed on the top of the frame structure 031; the unbalanced load friction can be reduced and the service life of the steel wire 051 can be extended by optimizing the rope outlet angle of the steel wire 051. In addition, a crisscross-shaped reinforcement rib can be set on the top of the frame structure 031 to improve the bearing capacity, or an integrated rain cover structure can be used to protect the hoisting mechanism, which can not only improve the convenience of operation, but also enhance the applicability of the equipment in harsh environments.

[0040] On the basis of the above embodiment, the vehicle body 03 further includes a guide structure 033 for guiding the transmission direction of the steel wire 051 led out from the winch structure 05; The guide structure 033 is a rotatably arranged rod body or a wheel body.

[0041] The guide structure 033 guides the transmission direction of the steel wire 051 to avoid deviation or entanglement of the steel wire 051 during the transmission process, ensuring smooth and reliable transmission of the steel wire 051, thereby improving the operating accuracy of the winch mechanism and the smoothness of the lifting and lowering action of the crane 04; specifically, the guide structure 033 can be set to an adjustable angle guide rod or a composite pulley group structure. The appropriate guide structure 033 can be selected according to the size structure of the drainage pipe 02 and the construction environment to adjust the direction of the steel wire 051, which can not only reduce the wear of the steel wire 051 and extend the service life of the device, but also improve the stability and efficiency of the lifting process.

[0042] On the basis of the above embodiment, the frame structure 031 includes a guardrail 0311, which is arranged around the standing position to limit the standing space of the operator, thereby improving the safety of the operator. The guardrail 0311 can be designed in a lifting style or a modular quick-release structure, which is convenient for adjusting the height or disassembly according to construction requirements. Specifically, it can be arranged as a telescopic structure supported by a gas pressure rod or a buckle connection of an aluminum alloy rod. Thus, the safety of the operator is improved while enhancing the flexibility and adaptability of the equipment.

[0043] The present invention also provides a working method of a bridge drainage pipe lifting device, using the bridge drainage pipe lifting device as above, comprising the following steps: A1: Move the vehicle body 03 to the set position on the top of the bridge; during the movement, the wheel assembly 032 of the vehicle body 03 must fit tightly against the outer surface, top surface and inner surface of the crash barrier 01 to ensure the stability and balance of the vehicle body 03 during the movement. During the movement, the operator must pay attention to the surrounding environment to avoid collision with other structures; A2: The hoisting frame 04 is hoisted to the top of the sliding path of the sliding part 041 by the hoisting structure 05; during the lifting process of the hoisting frame 04, the operator needs to pay close attention to the position and state of the sliding part 041 to ensure that it rises smoothly and avoids shaking or tilting; the steel wire 051 of the hoisting structure 05 can be guided by the guide structure 033 under the set scenario to ensure that the transmission direction of the steel wire 051 is stable; A3: Load the drain pipe 02 onto the rotating part 042 on the bridge; during the loading process, the operator needs to ensure the stability of the connection between the drain pipe 02 and the rotating part 042 to avoid loosening during the lifting and rotating process; when the bridge drain pipe lifting device is optimized to use the bearing body 0422, when implementing this step, the bearing body 0422 of the rotating part 042 can be adjusted according to the diameter and length of the drain pipe 02 to ensure that the drain pipe 02 can be stably loaded; A4: The hoisting structure 05 drives the lifting frame 04 to descend until the drain pipe 02 descends to the installation height. During the descent of the lifting frame 04, the operator needs to pay close attention to the position and state of the drain pipe 02 to ensure that it descends smoothly and avoids shaking or tilting. The descent speed of the hoisting structure 05 needs to be adjusted according to the actual situation to ensure that the drain pipe 02 can accurately reach the installation height. A5: In the working position, force is applied to the rotating part 042 or the drain pipe 02 to drive the drain pipe 02 to rotate from the outside of the vehicle body 03 to the inside. During the rotation process, the operator needs to ensure that the rotation is smooth to avoid the drain pipe 02 from colliding with the surrounding structure. The rotation angle of the rotating part 042 needs to be adjusted according to the actual installation position to ensure that the drain pipe 02 can accurately reach the inside position. A6: Move the drain pipe 02 to reach the installation position; during the movement, the drain pipe 02 can be separated from the rotating part 042, or maintain an installation state relative to the rotating part 042; specifically, in an ideal state of the installation position, the end face of the drain pipe 02 to be installed should be arranged opposite to the end face of the previous section of the drain pipe 02, and the axes of the two should be arranged collinearly. During the movement, the operator needs to pay close attention to the distance between the drain pipe 02 and the surrounding structures to avoid collision.

[0044] After moving to the installation position, the drain pipe 02 can be fixed to the connecting parts by bolts, welding or other connection methods to ensure that the connection is firm and reliable. During the connection process, the operator needs to check the sealing of the connection to avoid leakage and other problems in the future to ensure that the installation quality meets the requirements; after the installation is completed, the operator will re-fit the rotating part 042 and the sliding part 041, the winch structure 05 drives the sliding part 041 to rise, and the lifting frame 04 is reset to prepare for the next operation.

[0045] The above working method includes the steps of positioning the vehicle body 03, lifting the crane 04, loading the drain pipe 02, lowering to the installation height, rotating to the inside and moving to the installation position, etc., controlling the precise movement of the sliding part 041 and the flexible rotation of the rotating part 042, thereby realizing the efficient installation of the drain pipe 02; during operation, the vehicle body 03 moves along the arrangement direction of the drain pipe 02 to provide the operator with a working position at the bottom of the bridge, and the crane 04 drives the sliding part 041 to move up and down through the winch structure 05, and when the rotating part 042 and the sliding part 041 rotate through the longitudinal rotating shaft, the drain pipe 02 is accurately transferred from the outside to the inside.

[0046] The present invention also provides a working method of a bridge drainage pipe lifting device, using the bridge drainage pipe lifting device as above, comprising the following steps: B1: Move vehicle body 03 to the set position on the top of the bridge; B2: hoisting the crane frame 04 to the top of the sliding path of the sliding part 041 through the hoisting structure 05; B3: Loading the drainage pipe 02 to the rotating part 042 on the bridge; B4: The hoisting structure 05 drives the lifting frame 04 to descend until the drainage pipe 02 descends to the installation height; B5: In the working position, force is applied to the rotating part 042 or the drain pipe 02, thereby driving the drain pipe 02 to rotate from the outside of the vehicle body 03 to the inside; B6: Move the drain pipe 02 to reach the installation location.

[0047] In the process of moving the drain pipe 02 , the rotating part 042 is kept supporting the drain pipe 02 , and the movement includes moving the drain pipe 02 along the axial direction of the drain pipe 02 , and synchronously moving the supporting body 0422 and the drain pipe 02 along the telescopic direction of the telescopic body 0423 .

[0048] The above working method further optimizes the control mode during the movement of the drain pipe 02. The combined rotating part 042 is used as an auxiliary tool for the final positioning of the drain pipe 02, which is better than removing the drain pipe 02 from the rotating part 042 during the installation process. The length adjustment of the telescopic body 0423 can realize the synchronous axial and radial movement of the drain pipe 02, which can drive the drain pipe 02 to move to the vertical plane where the installation position is located, and be arranged in line with the axis of the previous section of the drain pipe 02. At this time, the drain pipe 02 can be moved along the axial direction of the drain pipe 02 to connect with the end faces of the two sections of the drain pipe 02, and the drain pipe 02 can be fixed by additional connecting parts. In this process, the precise adjustment of the screw mechanism or the hydraulic push rod can reduce the adjustment time of the operator, significantly improve the accuracy and efficiency of the movement, and greatly improve the applicability of the installation of complex bridge structures or special-shaped pipelines.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
